`Application filed June 3, 1908. Serial No. 436,615.

To all 'whom 'it may concern: Be it known that I, HOWARD S. KANTZ, a

citizen of -the United States, residing at Burnside, in the county of Clearield and State of Pennsylvania, have invented a new and useful Coupling, of which lthe following is a specication.

This invention relates to pipe couplings and has especial reference to that class'of pipe couplings, which are provided with means for .connecting the pipe sections together or nnscrewing them.

The invention has for its object to provide an improved pipe coupling of this kind, which can be quicklyand securely connected and disconnected and which is especially adapted to secure a rubber pipe yor hose to a metal pipe.

The invention consists of pipe coupling constructed and arranged as hereinafter set' forth and claimed.

Referringto the drawing, Figure 1 is a view of the invention showing the pipe coupling in locked position. Fig. 2 is a longi tudinal section thereof'. Fig. 3 is a. View in longitudinal section of a modification of the invention. Fig. 4 Iis a detail view of the coupling clamp in Fig. 3. Fig.,5 is an enlarged view in .longitudinal section of .a'

modication of one of the vpipesections in In the construction'of the coupling a metal tubular pipe coupling section 1 is provided, formed at its forwardV end with the head 2 in which is located'a tubular projection 3 eX- tending slightly beyond the head 2, and hav-4 ing a smooth exterior surface, the projection 3 forming with the interior surface of the head 2 an annular socket 4:. The-4 tubular coupling section 1 is formed in the rear with an exterior threaded portion 5 terminating at its rear end in an annular shoulder 6,: and having a tapering end portion 7lextending from the shoulder 6.- Mounted on and over lapping'the end portion 7 of coupling section 1, is the end ot a rubber pipe 8, and screwed onto the threaded portion 5 of section 1 is a sleeve 9 having a rearWardlyex-- tending tapering smooth which and the portion i `of sectlon 1 1sortion i0 betweenl clamped tl'e end of rlubber pipe 8, the latter hailing its end abutting agamstthe shoulder `6. `By means of the tapering end portions 7 and 10, the rubber 'pipe 8 will be firmly wedged and clamped between them by screwing the sleeve 9 on the section 1, and will be firmly held from pulling apart from the coupling section 1 owing to said tapering ends. 11 is the threaded end of: an iron pipe .having mounted thereon and 'projecting beyond the. same a threaded sleeve 12, which AWhen the pipe 8 is connected with the pipe 11 rojelcts over the tubular projection 3 aallnst a gasket 13 located in the inner end je? the annular socket 4. It will be seen that by means of this construction the gasket 13 isinclosed and will be thoroughly yprotected, and the gasket seals the connection between the pipe sections. The outer diameter of the tubular projection 3 is less than the inside diameter of the sleeve 12, by reason of which the threads of said sleeve are kept out of contact with said projection, and are thus protected from lbeing injured thereby. l v

'1n order to lockthe connected pipes together an eccentric U shaped lever 14. is pivoted ont-he pivot ins 15 projecting from A the sides of head 5, t e lever 14 having pivotally connected to its ends the 1G of a yoke 17. In Figs. land 2 the coupling is shown 'in locked position, the yoke 17. engag ing the pipe 11 behindi'th'e end, of sleeve 12,

and the lever 14 preferably standing out from the coupling whereby -it may be easily handled to quickly unlock the couplii'1g,l The position of the lever' 14,- arins 16 and yoke 17 when unlocked is shown in dotted lines in' Fig. 2. v l

In the modification in Fig. 3 there is pro 90 vided a tubular pi e coupling head 13:, split,v as at 19, with jthe gauges 20, connected by a bolt 21 extending through holes 22 in said flanges anda nut 23 by means'ofwhich head 18 may be clamped in position.' ihe: a5 head 18 is formed with a cylindrical socket' portion 24 having an internat annular shoulder 25 against which is seated a gasket v26'. Extendin through ,the heady' and: l

iprojecting slig tly bey'pnd, the eameip, :the "10c-f nd df a rubber pipe 'or hose 27^`having or` cated within the same a short'piece est metal pipe 2S extending tn the outer Aend of' pipe 27, and servinffas'fa ri id' lining'or support. Thpipe`g27 locted- 1n the socketportion 1.05 24 forms with \the i;nner surface thereof an annular socket'29.. Upon the threaded end of a metal ,pipe 30 is screwed la sleeve 31 projectingbeyond the pipe 30, which when the pipe 27 is connected wlth the pipe 30 1 projects over the end of pipe 27 against the gasket 26 at the end of annular' socket 29.

j ally mounted on the It will be seen that by means of the adjust-v I able clamping head 18, the rubber pipe 27 will be tightly clamped lto the pipe 28 and held from being drawn out of the head 18. Y The coupling is locked similarly to that in Figs. l and Q ,by an eccentric lever 32 pivotivot pins 33 project- 111g from head 18, ang a yoke 34 engaging pipe 30 behind the end of sleeve 3l.

In the modification in Fig. 5, a short metal pipe 35 with espiral rib 36 on its eX- to end thereof, is forced into the end of a rubber pipe 37 ex tending through and projecting slightly beyond a pipe coupling head 38. The head 38 is formed with a cylindrical socket portion 39 having a shoulder 40. against which is Seated a gasket 41. By means f the spiral rib 36 on pipe 35, the rubber pipe 37 will be firmly held in the head 38 and prevented from being drawn out therefrom. An eccentric lever is pivoted on thepivot pins 43 projecting from the'sides of the heed and has a yoke as in the other cases.

Having described the invention,l I claim t` In a pipe coupling-a member having a threaded end, :in interiorly threaded sleeve screwed on said end and projecting therefrom, a second member having at its end an annular socket to loosely receive the projcting end of the aforesaid sleeve, the walls oi the' socket being spaced from the threads of said projected end ofthe sleeve, anda clamp carried by the socketed member, end engageable with the end of y the sleeve which is screwed on the first mentioned member.

In testimony that I claim the foregoing as my own, have hereto eiixed my signeture in the presence of two Witnesses. i
